Option to Renew



Provided that during the Term of this Lease, Tenant has been in full
compliance with each and every term, covenant and condition of this Lease, and there has been no breach or default herein or hereunder, Tenant shall have the right to extend the term of the within Lease for one (1) additional five (5) year
period commencing with the End Date. In order to effectively exercise the within option, Tenant shall give written notice thereof not less than twelve (12) months prior to the End Date, time being of the essence. In the event of the effective
exercise of the within option, the term hereof shall be extended for an additional five (5) year period on the same terms, covenants and conditions as set forth in the Lease, except for the within option and with the further exception that the
per annumBase Rent for and during the first Lease Year of the extended term shall be Fair Market Rental as indicated below.



The term Fair Market Rental is defined to mean the prevailing market rate for comparable property and comparable buildings in the greater New

Within thirty (30) days of the exercise of the option to renew, the
parties shall each appoint a licensed commercial real estate agent located in the Greater New Haven area, which real estate agents shall select a third such agent. Within twenty (20) days thereafter, the three real estate agents so selected
shall determine the Fair Market Rental of the Demised Premises, as of the option date.



If either party fails to select a real estate agent within the time period set forth above, the real estate agent selected within the required time period alone shall determine the Fair Market Rental.



The determination of Fair Market Rental as outlined above shall be conclusive
on the parties. The real estate agents chosen by the parties shall give notice to the parties stating their determination and shall furnish to each party a signed copy of that determination.



Each party shall pay the fees and expenses of the real estate agent appointed
by such party and one-half (1/2) of the fees and expenses of the third real estate agent properly incurred.



---

In no event shall the Base Rent for the first Lease Year of the extended period be less than the Base
Rent for the Lease Year September 1, 2010 through August 31, 2011.

modified in any respect, except as set forth herein; (c) no rent has been paid for any period commencing after September 1, 2005; (d) no default exists by Landlord or Tenant under the Lease and Tenant has no defenses, offsets or
counterclaims which it could assert against the payment of rent and/or the performance of the other terms, covenants and conditions of the Lease; and (e) this statement is being provided by Tenant in order to induce Landlord to amend the Lease
as set forth herein with full knowledge that Landlord is relying upon the statements and representations herein made by Tenant.
